How much accurate ultrasound in 31week to tell the gender of the baby?

At 31 weeks of pregnancy, ultrasound is generally quite accurate for determining the baby's gender, with accuracy rates often exceeding 95%. By this stage, the baby's genitalia are sufficiently developed and can usually be clearly visualized. However, factors such as the baby's position, the quality of the ultrasound equipment, and the technician's experience can affect the accuracy. It's always best to confirm the findings with a healthcare provider.
